Human beings are known to deteriorate naturally with age in a process called aging, which is a psychological change in the human body leading to senescence. When human beings age, the biological functions of their bodies, resistance to diseases, and their ability to adapt to stress declines (Aldwin & Gilmer, 2013). The causes of aging have remained uncertain for a long time, and the process of aging has remained a biological puzzle. Nevertheless, scientific researchers that have set their sights on explaining the causes of aging have attributed the primary causes of aging to both programmed factors and damage-related factors.
Firstly are programmed factors of aging, which are to a large extent genetically based. According to the programmed
The elderly population is growing rapidly and now makes up greater than thirteen percent of the United States population. (APA, 1994). With such a record growth, there are different aspects to aging that are still being analyzed. Many may think of reaching late life as a rite of passage, but many face this time with a different view. Through the movie "UP', we are granted an opportunity into view the struggles of an elderly widowed man by the name of Mr. Fredrickson and the challenges in which he faces in his later life. The movie, takes one on a journey through his sorrows and his triumphs until he realizes what the true meaning of happiness is.
The humanity of aging is a concept sometimes hard to grasp. Understanding why we are
Humans undergo several stages during their lifetime including growth, development, reproduction and senescence. Senescence is defined as the deteriorative biological changes that organisms experience as they age eventually leading to death. These changes include low metabolism, a weak immune system, memory loss, poor vision and loss of hearing. Senescence begins in humans during their post-reproductive years. However, gerontology research has shown that individuals who reproduce late have longer life spans compared to individuals who reproduce early. Nonetheless, it does not indicate that senescence is inevitable. All organisms experience senescence,
Within the last century, and even merely in the past decade, incredible advancements in technology have allowed modern medicine to rapidly progress to extraordinary levels, leaving scientists with unprecedented understanding of the human body, and of the aging process especially. While the field of gerontology has flourished as a result and knowledge of physiological changes in the aging body increased, scientists still only have a some-what fundamental understanding of the normal aging brain, and even less of abnormal age-related changes in the brain.
Aging is an inevitable part of the lifecycle. At some point in their lifespan, every person will experience changes that occur during the process of aging. Many changes that occur, such as loss of muscle tone, decrease in vision, decrease in hearing, and decreased bone mass, can be attributed to the natural processes that occur as you age (Robnett, Bolduc, & Murray, 2015). The progression of these changes, however, can be influenced by many factors in an individual’s life. The effects of aging on an individual are not only dependent upon genetics, but also upon their physical and social environments and their cultural, personal, temporal, and virtual contexts (Brossoie & Chop, 2015).
Aging is a part of life not everyone wants to accept. There are many theories on aging and I would like to focus on the Stochastic Theory. The Stochastic Theory is “based on random events that cause cellular damage that accumulates as the organism ages” (Grossman, S. & Lange, J., 2018, p. 55). Within this theory there are four categories but I am only going to focus on two: Wear and tear theory along with Connective tissue/cross-link theory.
A majority of people tend to object to exercise during the adolescent years because the individual is in the early stages of life where they are not fully developed. Exercise is not simply made for its look-good, feel-good sensation that it provides; it is positively correlated to longer life expectancies, which we associate to healthy lives. One of the most important businesses to help out with exercise are the health clubs that are increasing in popularity as time goes on. The gym industry thrives off of their clientele, who pay, on average, fifty-eight dollars per month for membership, where thirty-nine of those dollars go to waste from under utilization (Gym Membership Statistics). The hours of operation that the gym is available forto
According to (Zastrow & Kirst-Ashman, 2016) there is a myriad of challenges facing older adults throughout their later years of life. The issues range from failing eyesight to aching joints, but the good news is that the aging process is an individual process. The bad news is that it is a process no human being can escape this process in the genetic makeup of every human on planet earth. Our voice weakens, our skin wrinkles, our gums in our mouth
Normal aging is a gradual decline in certain processes (Gladyshev, & Gladyshev, 2016). The decline is not static and can be increased or reduced depending on choices made (Gladyshev, & Gladyshev, 2016). Changes commonly attributed to aging include declines in the five senses, most organ systems, appearance and brain function (Tully, 2016). The five senses include reduction in taste buds, smell, ability to hear high frequency sounds and speech discrimination, reduced ability to see in the dark and a reduction in tactile sensory (Tully, 2016). In the organ systems there is a reduction in the hearts response to work, bone mass, skin turgor, vital capacity in the lungs, renal and colon function (Tully, 2016). Most notable is the age-related changes
We live in an age obsessed society. Just a quick peak around the local pharmacy shows no shortage of "anti-aging" creams and solutions. We live to look and feel young yet it's losing battle from the start. Ultimately, we can only delay the natural effects of aging for so long. That is unless you are like these five people found on YouTube. They are immune to aging. However, you'll find out that it's not all it's cracked up to be.
In order to better understand aging-associated diseases, it is first necessary to define what aging is. Aging is a complex, multifactorial process of harmful mutations in cells and tissues that are accumulated over time and result in an increased risk of disease and, eventually, death (Tosato, Zamboni, Ferrini, & Cesari, 2007, p. 401). Contrary to the belief that aging can be cured through medical advances, it is scientifically accepted that, while human life expectancy has increased, the human life span has remained largely unchanged for the past 100,000 years (Tosato et al., p. 401). Therefore, future developments in aging research ought to focus on addressing treatment and prevention of major aging-associated diseases that will
The biological theory of aging is connecting the process that caused organism to develop by a process of evolution. It is belonging to the essential nature of aging such as decreases body function like lung capacity or loss of brain cells. These could lead people to become lower in physical function including putting the person’s life at dangerous illness and makes easier to death. The error theory is the cause of aging in the normal function of the body which is staying over time. Moreover, these biological and error theories are related both two main categories and those theories might interact with each other in complicate way. Because programmed and error theories had been proposed to describe the process of aging, but none of them appears
The way God created us as humans is a life cycle where eventually late adulthood comes with the biology of aging. Santrock (2013) describes five different theories of why humans age (p. 541). The evolutionary theory explains that aging is more of a natural selection process, and diseases occur in the elderly because they “would have been eliminated” if they were in younger people (Santrock, 2013, p.541). Cellular clock theory describes how cells get tired of dividing after they have been reproducing for so long (Santrock, 2013, p.541). Free-radical theory explains when “cells metabolize energy the by-products include unstable oxygen molecules known as free radicals” (Santrock, 2013, p.541). The unstable oxygen molecules can damage DNA and other structures inside the cell (Santrock, 2013, p.541). Mitochondrial theory describes how aging occurs because of the mitochondria essentially wearing out and becoming less efficient (Santrock, 2013, p.542). Mitochondria are the cell’s “power house,” and they convert energy inside the cell (Bailey, 2008). The last theory, hormonal stress theory, illustrates the effects of stress, especially long term stress, on aging (Santrock, 2013, p.542). Stress released hormones which depress the immune system making people more susceptible to disease (Santrock, 2013, p.542). There are many theories about why human’s age, and all of them may be true, but regardless aging is inevitable and so are its effects.
Aging is the process of becoming older, as we age, multiple mutations occur that concern all the processes of aging well as it compromising a number of different genes. There are many theories of biological aging, such as the Cellular Aging Theory, Immunological Theory, and the Wear and Tear Theory. The Cellular Aging theory describes the process of aging in which cells slow their number of replication, thus giving each species a “biological clock that determines its maximum life span” and how quickly one 's health will deteriorate(Hooyman, 42). After a certain number of years, each cell which follows an apparent biological clock starts to replicate itself less, thus the specific individual or species slowly deteriorates. This theory gives
Causes of aging are very uncertain. Besides, there are several factors which predispose an individual to premature aging. Current theories suggest that this process occurs to due to cellular damage such as DNA oxidation by free radicals causing
